        * gdk/gdkdisplay.h:
        * gdk/gdkinternals.h:
        * gdk/gdkwindow.[hc]: Add gdk_display_supports_composite() and
        gdk_window_set_composited().

        * gdk/x11/gdkevents-x11.c:
        * gdk/x11/gdkdisplay-x11.[hc]:
        * gdk/x11/gdkwindow-x11.[hc]: X11 implementation.

        * gdk/win32/gdkdisplay-win32.c:
        * gdk/win32/gdkwindow-win32.c: Dummy win32 implementration.

        * gdk/quartz/gdkdisplay-quartz.c:
        * gdk/quartz/gdkwindow-quartz.c: Dummy Quartz implementation.

        * gdk/directfb/gdkdisplay-directfb.c:
        * gdk/directfb/gdkwindow-directfb.c: Dummy DirectFB implementation.

        * tests/testgtk.c: Add a "composited window" test.
